Plumbers Warn: Saturated Ground Makes Sump Pump Inspection Urgent

Plumbing professionals across the United States and Canada are reporting a significant spike in sump pump service calls as 2026 gets underway. Roto-Rooter, North America’s largest plumbing and water cleanup provider, is tracking a 32% increase in calls compared to the same window last year. During the previous spring season, call volume climbed 75% between March and April before reaching its highest point in May. Early indicators suggest this year is already moving faster than that trajectory. With heavier-than-average winter snowpack now melting across wide stretches of both countries and rounds of heavy rainfall already arriving, sump pump systems are being pushed harder than they have been in years. Plumbing professionals are cautioning that the time available for preventive action is shrinking rapidly, with demand expected to build through April and May.

To help property owners get in front of potential problems before they escalate, Roto-Rooter’s team of plumbing experts has outlined the five most common sump pump failure points along with practical guidance on how to address each one.

“The volume of sump pump-related calls coming in this season has been notable, and it is not limited to homeowners. Businesses are calling too. The peak has not arrived yet, and that alone tells the story of what is ahead,” said Dave Jones, Master Plumber and VP at Roto-Rooter. “When soil saturation reaches this level, any sump pump that has not been inspected is essentially operating on borrowed time.”

The 5 Most Common Sump Pump Failure Points

1. Float switch failure – The single most common cause of sump pump problems, float switch failure can cause a unit to run without stopping or fail to turn on at all. Property owners are advised to remove the sump pit cover and confirm that the float is not tangled, pinned against the pit wall, or coated in residue. Manually lifting the float to verify that the pump activates is a basic but important step. If the pump still does not respond correctly after the float is cleared, a professional should replace the switch before spring conditions reach their peak.
2. Motor burnout – Rather than a sudden event, motor burnout is typically the accumulated result of smaller issues that were left unaddressed. Before assuming the worst, owners should inspect the GFCI outlet and breaker box, since a tripped circuit is sometimes the only problem. If the outlet is confirmed to have power and the pump remains completely unresponsive, the unit will require full replacement.
3. Worn or damaged impeller – A compromised impeller reduces the pump’s ability to move water efficiently and places increasing stress on the motor over time. Owners should unplug the unit, remove it from the pit, and check the intake screen for any debris that may have accumulated. Flushing the inlet and discharge openings with a garden hose can resolve minor blockages. If reduced performance or unusual noise continues after cleaning, the impeller is likely cracked or warped and will need to be replaced by a professional.
4. Clogged or frozen discharge lines – A particularly common issue in early spring, a blocked discharge line forces water to back up inside the pit with no outlet. The recommended first step is to inspect the exterior discharge opening for ice or debris. If the line is frozen, a heat lamp or hair dryer can be used to thaw it safely. Open flames should never be used. If the blockage is located further inside the underground piping, a professional drain cleaning service will be necessary to clear it completely.
5. Check valve failure – When the check valve fails, water that has already been pumped out flows directly back into the pit, trapping the pump in a continuous cycle that leads to rapid burnout. Owners should unplug the pump, place a bucket below the valve, remove it, and install a replacement. The directional arrow printed on the valve body must face upward and away from the pump during installation. If the pipe configuration requires cutting PVC or backflow pressure is strong enough to cause vibrations in surrounding walls, a licensed plumber is strongly recommended.

The Financial Stakes

The cost of a sump pump failure during peak spring conditions can be substantial. Basement water damage restoration is estimated to run between $5,000 and $25,000 depending on the extent of the damage, and a single inch of standing water alone has the potential to cause up to $25,000 in losses. The financial exposure is further compounded by the fact that standard homeowner’s insurance policies generally do not cover flooding caused by groundwater intrusion or sump pump failure, leaving most property owners to absorb those costs entirely. A professional pre-season inspection, by contrast, typically runs between $300 and $500 and is widely considered one of the most cost-effective investments a homeowner can make heading into spring.

“In 25 years in this business, the springs that do the most damage are always the ones that follow the heaviest snow seasons. When the snow starts to melt, a lot of people assume the risk is behind them. It is not. That water is moving through the ground and finding every weak point it can. Without a functioning sump pump, it will enter the basement, saturate flooring and carpeting, and damage everything stored in that space,” Jones said.
